RESUSCITATING APPARATUS.

SPECIFICATION forming ert of Letters Patent No. 587,891, dated August 10, 1897.

1 Application filed November 18, 1895. Serial No. 569,331. (No model.)

To all whom it mn-z concern- Be it known that 1, JAMES C. WALKFIR, re-

, inafter appear, my invention consists in an apparatus for the purposes stated, such as will be first described in detail, and then specifically pointed out in the appended claims, reference being had to the accompanying drawings.

Figure 1 is a perspective view of my respiration apparatus, showing thesame as arranged for use. Fig. 2 is a similar view of a portion thereof, showing the first position and first treatment of the patient. Fig. 3 is a view illustrating a modified arrangement of parts, as will hereinafter fully appear. Fig. 4 is a detail view of the adjustable support for the table, hereinafter referred to. Fig-5 is a sectional view of one of the automatically-operated pumps. Fig. 6 is a vertical section of one of the vacuum-cups. Fig. 7 is a perspective view of the table; and Figs. 8, 9, and 10 are detail views, hereinafter referred to. Fig. 11 is a perspective view illustrating my improved apparatus equipped with a double-acting cam for operating the several pump and air devices, hereinafter referred to; and Fig. 12 is a view of a portion thereof, taken practically on the line 12 12 of Fig. 11.

In the practical construction my resuscitating or respirating apparatus comprises a framework, preferably of six uprights a a a, nine cross-pieces a a a a and a and eight end cross-pieces a which are formed together, as shown in Fig. 1, and may be either .hard wood, metal, or both, as may be best suited for the purpose.

I) b and b b are ellipsoidal-shaped steel guides,which have a thin inner edge-say oneeighth of 'an inch, increasing in thickness to one-h alf or three-fourths of an inch, as may be required to givefstrength for the purpose hereinafter stated-"such guidesbeingrig'idly fixed at their outer edges at the middle of the cres- I cent to four tubes b which move back and forth over four metal rods b which are'rigidly fixed to the upright frame members a and braced by four braces, two of which are rigidly fixed to the uprights a, while the other two are secured to the frame members a a. The tubes or sheaths b are also held steady by two braces connected to the crescent'guides, as shown.

c cindicate sprocket-wheels which are fixed on axles journaled in cross-pieces a a, a and a as shown, and both sprocket-Wheels, bya suitable sprocket-chains are worked by the crank c on thev upper axle 0 The wheels 0 c,

being the same size, worksynchronously. On

the sprocket-wheel axles, back of the wheels, are fixed four arms 0 having small grooved wheels in their outer extremities which engage with the inner edges of the ellipsoidal ton-shaft d of an air-pump d, which is held securely braced in position on the cross memhere a and a as shown most clearly in Fig. 1.

The pump d, the construction of which is most clearly shown in Fig. 5, comprises a body D, a piston 19, the shaft deof which connects with the rod 0 At the bottom the body D has a small valve-chamber p in which is a slip-valve p, to which is connected a rod p, which passes into the body D and terminates in a head portion 19, which is adapted to bear on an elliptical or other spring or cushion member 1), the ends of which'rest on the bottom or base of the pump, for a purpose presently explained. p indicates an openingin the side of valve-box 19 over which the slidevalve p isheld to move, it being of a sufficient size to cover the part 19 From the valve-box p of thepump d extends a rubber tube d which leads to a casing or box d hereinafter explained.

On the inner end of the axle of the lowe sprocket-wheel c and disposed between the I cross-pieces a and a isfixed asprocket-wheel connected by' a chain with sprocket-wheel c, the axle of which is journaled in the crosspieces '1 and a, as shown. The inner end of this axle has a crank connected by rod 0 with the piston-shaft d of an air-pump 01 which is fixedly held in position by braces secured to the framing, as shown. The air-pump d is of substantially the same construction as pump 01, (illustrated in Fig. 5,) and therefore need not be referred to in detail.

From the valve-box'of pump (1 leads the rubber tubes (1 d which pass to the arm boxes or sheaths 01 (1, made airtight, in which the arms of the patient are adapted to be held. A third tubed also connects with the valve-box of pump (1 which joins such box to a vacuum-cup d, which is kept in position by a rod (1, which is held to slide in a tube d and held to its adjusted position by a thumb-screw d, such construction admitting of the rod 01 being lengthened or shortened to size of patient.

By referring now to Fig. i it will be seen that tube (1 has an extension d, which connects with a crank e onthe end of axle 0 which is madeadjustable, as shown, so that it can be lengthened or shortened to suit the size of the patient. d indicatesthe leg-box, formed of wood or other material and made air-tight and of sufiicient capacity to inclose the feet and legs, up to the hips. To this legbox, at the upper edge e is fixedly secured flap.

- to extend inwardly from the tube, the inner a rubber-cloth adapted to extend around the body which is joined to a pneumatic tube 6 which alsoextends around the body in connection with the rubber cloth. This tube has two flanges orfiaps of rubber cloth, one in-- By reference to Fig; 9 the flap e will be seen circumference of which, being contracted in its natural condition, is shown in dotted lines.

It will also be observed that the flap e is at-' .tached to about the middle of the outer body of the tube, the said flap 9 having its outer V edge considerably contracted in circumferonce from that of the tube. The flaps are of rubber cloth and made to contract and fit close to the hips and shoulders of the patient.

The arm-boxes, before referred to, are similarly made of wood or other suitable material from the outer ends to the edges e e, to which (see Fig. l) are attached rubber-cloth. portions which connect with the pneumatic tubes e e and are of sufficient capacity to inclose the. arms and hands. These cases or boxes, as also the leg-box, are made with as little internal spare space as possible and may be of different sizes to suit patients. The tubes e are madeto fit as close as f possible around the arms in the arm-pits and over a part of the shoulders, they being held in position by elastic lacings'underneath the shoulders, as also across the breast, as shown' by the dotted lines on the tubes in Fig. 1.

The pneumatic tubes are made with flaps and in similar manner as described above for the leg-box, so that in'these, as also in the legbox, when the air is compressed-by the pumps the internal flap will be forced into the crease between the pneumatic tubes and the skin of the patient, and thus prevent the escape of the air from the casin g or box. When the air is withdrawn from the casings by the pump, 9o the'outer flaps will be drawn into the crease between the said tubes and the skin of the patient, and thus prevent air from going into the casings, whereby a partial vacuum and compression is alternately created .in the said casings or boxes. 7

Referring now again to Fig.1, it will be observed that the outer ends of tubes b b upper set, are connected by short links f f with levers f f, which extend through apertures in the ends of the studs f f (fixed to the main framing, as shown) down to the tubes below b and linked thereto, as at ff. With the last-named tubes 1) are also connected levers f f", joined theretoby short links f f. These levers f f 6 pass down through apertured studs f and have at their lower extremities holes f 8 f through which the levers 1 pass, and when properly adjusted are fixed by the thumb screws f f. The inner extremities of the levers f f -are fixed to the vacuum-cups f f adapted to be pressed against the sides of the patient, as shown in Fig. 1, which cups are connected by rubber tubes 9 g with the air-pump g (1 indicates a supplemental or breast cup, which also connects with the pumpg by a branch tube 9 running out from g, this lat ter connection being regulated by valve 9 The several vacuum-cups are constructed in1the manner clearly shown in Fig. 6 and has comprise a body portion it made of glass or other suitable material, having one end open, which end is adapted to be applied to the body of the patient. The rim of the cup is fixed in or to a pneumatic tube is, from which ex- In Fig. 6 is shown the breast-cup d, similar to cup f, connected for ordinary use by rubber tube (1 with the valve-box p of the lower air-pump (1 This cupd is held in position and connected to 'rodd which slides in a tube (Z (see Fig. 1,) and when properly adjusted is held fixed by a thumb-screw c1 and tube (1 being connected by rod'd with the small crank e, which passes through an aper- .trode in cup f on one side.

ture in the end of axle c and held fixed by screw 6, whereby the stroke of the crank may be lengthened or shortened, accordingly as may be required by the size of the patient.

h, h', and 71 are Foradic batteries. One pole of battery It is connected with an electrode at the base of the neck of the patient and the other pole to an electrode placed at the lower end of the spinal column or with the feet of the patient. One pole of battery h is connected by a wire with a sponge-elec- The other pole is connected to the electrode in the cup f on the other side of the patient. One pole of battery k is connected to electrode in cup (Z and the other with an, electrode under the body, as will hereinafter be more fully explained.

f j" indicate studs which are fixed to sheaths Z Z, (see Fig. 2,) which are held to slide on uprights a and having each an aperture in front showing a scale of inches on the -uprights, and when properlyadj usted are fixedly held by the thumb-screwsJ Z, such studs being braced, as shown, to the sheaths. The objectof this last-described construction'is .to increase or lessenthe movement of the lowerextremities of the levers f f, accordingly as may be required to suit the size and expansion of'the chest of the patient. When the studs are dispgsed at the middle of the levers, (t e upperijstu s f" f being permanently fi/ '-8d at the middle of the levers f f',) it is evident that so much movement of the upper end of levers caused bythe ellipsoidal disks will cause a like movement of, the lower ends .of the leversf Such movement of the: said ends of the lower levers f f is dependent on whether the studs f f are placed at the middle,- above, or below the middle of the levers f. If at the middle, the nnovement of the lower extremities will "be the same as the upper extremities; it above the middle the movement of the lower extremities a is greater than the upper, and it' 'below the tremities of the levers f f can be easily ad-' justed to the patient.

g represents an exhaust air-pump worked by hand separately from the apparatus and i which is also connected with the vacuumcups d and f by rubber tubes g, g, and 9 the object of which is to keepa-continuous vacuum in the cups, except as may be varied in cup d, which is adapted to be cut off from the pump g by the valve 9 (See Fig. 1.) Cup d is also connected by tube d with pump (F, the object of this connection being to make the vacuum and compression in cup d synchronous with cups f f if found advantageous.

In Fig. 3 is shown a modification of the mechanism shown in Fig. 1. In this latter construction instead of using the ellipsoid disks Z; I) ellipsoidal cams B B are provided, and instead of the tubes 1) being fixed to the disks, as shown in Fig. 1, small grooved wheels are fixed at their inner ends, which play against the cams, and thus by the movement of the cams the tubes 12 are 'moved back and forth, as before described.

Spiral springs m are provided tokeep the tube and wheels in contact with the cams and also to relieve the levers f f from the strain of this movement.

In Fig. 2 the drowned patient is shown on the table 0 (the construction of which is most clearly shown in Fig. 7 with his back uppermost, his forehead resting on the low'cushion m and his face protruding inthe opening 11., his chin resting on the edge of the opening n, which will serve to keep his mouth and;

throat open, and with the cups d and f placed against the body, asshown, the table being considerably elevated at the foot end.

At this time none of the 'cups are connected with the pumpsd' and (1 but a vacuum is produced in all by the pump 9?. time the cups f f are moved laterally by the levers f f and alternatelypress in and pull out the sides of thepatient, while the IIO At this cup at moves slightly and synchronously with cups f f --2'. e., when these cu'ps f pull the sides out'the cup d ,through the medium of the lever d andcrank e, pulls the back up, and when the sides of the patient are pressed in the cup (1 presses downward, so that this movement will expel all the Water out of the, lungs and stomach of the patient. When this is accomplished, the cups are loosened and the-patient turned. over on his back, as shown in Fig. 1. His arms and legs are then quicklyjplaced in the arm and leg boxes or sheaths above described and the same connected with the pumps (1 and d bythe tubes (1 at, and al after which the cups f f are replaced on the sides and the cup (1 on the chest of the patient. The table is then let down to a level with the stop-knobs n n, the-air is' exhausted from the cups, and the ellipsoid guides connected withthe arms a so that such arms (or the long axis of the cams) will continue to work at right angles,

. will respectively begin and end their stroke at the same instant by a proper adjustment and thereby when the upper ellipsoid guides are widest apart the lower ellipsoidal guides will be to their closest or drawn-in position, as clearly shown in Fig. 1, it being manifest that practically the same operation is effected i by using the cam devices B B and the ad-- justing parts connected therewith instead of the ellipsoidal-guide construction- .It should be stated that in practice the.

pumps d and d are so arranged thatthey of their cranks,-so that the piston of the pump the upper horn of the right disk, while the i i is ' ing'slt will be apparent that the expansion-bf (1 will begin to descend as the small wheels in the arms 0 come in contact with the *upper horn of the ellipsoid guides, (the right arm c in upper guide comes in contact with left arm 0 comes in contact with the lower horn of the left guide,) such piston continuing to descend until ,the arms in the upperguides reach the center of the disks exactly opposite to the tubes b b As the arms reach these horizontal points the aforesaid piston.

will begin to rise and will complete its movement as the arms pass from touch of the upper crescent disk.

By following the arrangement of the sev-. eral arts as described on Fig. 1 of the drawthe upper guides through the several levers and cups expands the chest, while the expansion'of the lower guides forces the upper end of the levers f f outwardly, and thereby causes the lower extremities to move inwardly, thus compressing the chest-natural breathing. The pumps d and d acting synchronously with the guides when the chest is expanded compression of air isproduced in the leg and arm b0xes,thus causing the blood to flow therefrom to the trunk of the patient,

and when contraction of the chest takes place the said pumps (1' and. 01 cause a partial vacuum in the leg or arm boxes, and thereby draw the blood from thetrunk into the extremities, and again when expansion of the chest takes place compression of air int-he leg and arm'boxes occurs and again forces the blood into the trunk, thereby tending to produce natural circulation, the electric devices used in connection with the circulating devices described naturally aiding to produce a successful result of the operations stated.

- Referring new again to the pump devices d or d, it should be stated that when the pision is up the spring 10 by means of the head p on the small rod p pushes it up. This draws the valve 11 over the opening p and shuts out the passage of air through the said opening p, so that when the piston starts down the air in the pump is forced through the rubber tubes into the leg and arm boxes, and thereby produces the compression of air 'such table on same level as legs m.

therein, before mentioned, until the piston and draw-valves 19 over the opening p. The

piston then draws the air through the rubber tubes out of the boxes and produces a partial vacuum, as stated, until the piston'passesthe opening .10 The air then rushes through this and the tubes and produces an equilibrium in the arm and leg boxes, thusproducing alternately as the ellipsoid disks are moved compression and rarefication of air in the leg and arm boxes.- The movement of the pump-pistons is caused by the -rods c,

"and which are linked to the cranks on the inner ends of the axles of the small sprockctwheels 0 and c, which are half the size of the main wheels c and c, as before stated, and are so geared that half the revolution of c and 0 will produce a complete revolution of the small wheels to cause the reciprocal thrusts of the pistons.

It wilt-manifestly appear by referring to Fig. 1 that as the revolutions of wheels 0 and 0 correspond and synchronize with the revolutions of crank c the-lower disks by means of the wheels 0 and care made tosynchronizewith the upper disk, though set at right angles'with such upper disks, so that when the'upper disks begin to expand 'the lower too ones begin to contract-in the .manner here-' tofore described.

The table for the patient, the construction of which is most clearly shown in Fig. 7 has permanent legs m m and adjustable legs m m which are longer than legs m and which pass through the lugs or cars 'm" 'm, securedto the table. Attached to the legs m are spring-ratchets n n, which pass through the lugs or cars m m, by means of which the foot end of the table may be raised to any desired height and so held by the ratchets. n n are n knobs on which the table may rest to make m indicates a low movable-cushion over which the foreheadiof patient is adapted to' rest. 1; indicates an openingior slit cut in the table of sufficient size to admit the face of patient with his chin resting onthefedge of said opening n. This will open his mouth for escape of water, the incline of table also placing the throat and chest in the best position for the escape of the water.' I

In Fig. 11 I have illustrated a simplified construct-ion'of my apparatus. In-this construction but a single cam member B is used,

which is of elliptical shape and provided with arflangedlperipheral member B. Such can be made fast to the crank-shaft c, which shafthas a mainsprocket-wheel a? which is geared with a smaller sprocket-wheel c on a shaft '0, held below the shaft 0 journaled on a supplemental frame-section which shaft 0 has connected alternately-projected crank members.'cand 0 one of which, 0 connects with the breast-cup-operating rod 11 while the other, 0 connects with the pis= ton-rod of the pump (1 which in the present construction supplies and exhausts air from the leg and arm boxes, as clearly'shown in the drawings. The side cups are operated by the oscillating rods f which have their upper ends connected to the reciprocating plunger-rods 12 to the ends of each of which are secured a pair of roller-guides Z7 11 which project and-fit inside of the cam-flange and a single roller-guide b which bears on the periphery of such flange, as clearly shown in Fig. 12. By this construction it is manifest that the plunger b b will be moved uniformly outward as the shaft 0 is revolved, and such operation will serve to act upon the pump and the cup-operating devices in a manner clearly understood by reference to.

the drawings. 1

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete operation and the advantages of my invention will be readily apparent, it being understood that many changes in'the details of construction maybe made without departing from my invention and the scope of the appended claims. 1
